How to set Ipad auto lock after 1 hour

Sorry, not possible.

The maximum auto-lock period is 15 minutes. Beyond this, the only available option is to set auto-lock to Never.

Under touchID or FaceID & passcode, if you use touchID or use FaceID, then “immediately” is the one and only option.

Under display and brightness, the auto lock timeout default would be 2, 5, 10, 15 minutes or never. But an employer account security settings can remove any of those ad force limitations on the device. That is a consequence of your employer allowing you to use your work account on a personal device.

Go to

Settings

Then scroll way down (6th one after General which is in the 3rd section) to TouchID & Passcode.

Will have to enter your passcode to make these changes.

Then go to 4th section of choices to Require Passcode and then to the right in light gray you will see the word 'After'

NOW you can control the intervals for the passcode request SEPARATE from the Autolock time. It will most probably have 'immediately' checked off since, as stated above, it's the default. But that is what makes the autolock more than just a screen saver.

Now if finger print is used, this is all sort of moot.

But for those using a passcode it resolves the issue of having to type in the passcode all the time.

Note too that even the option of “never” for auto lock timeout may not be available if you have a work exchange or Office365 account set up, or any other managed account in the device which overrides the iPadOS defaults.
